14 Services ( View All )


Intravenous sedation is a general anesthesia that allows patients to remain awake during their dental procedure, but deeply relaxed and more comfortable. Sometimes known as twilight sleep, IV sedation does not usually put the patient to sleep, but since they feel relaxed and often lose their memory of the procedure, it can feel as if they are asleep. However, the patient is awake, able to listen, and follow and instructions from board-certified periodontist, Dr. Roberto Porras of Texas Periodontal Associates in Houston. By numbing the area of the mouth to be treated along with IV conscious sedation, Dr. Porras can help patients get through their treatment with minimal discomfort and pain.

Reasons for IV Sedation

  • To reduce anxieties and fears
  • To improve patient comfort
  • To prevent gagging
  • Allows the patient to remain conscious


Patients should talk to their doctor about restrictions on the day of their IV sedation, but patients should not eat or drink for 8 hours before their procedure. To prevent anxiety and discomfort during the actual sedation injection, the doctor will usually prepare the injection site by applying a numbing cream. Once the local anesthesia has taken affect, the doctor can inject the intravenous sedation medication into a vein near the surface of the skin. The most common drugs used during IV sedation are anti-anxiety sedatives (benzodiazepines), like Midzolam and Diazepam. A staff member will monitor the patient’s pulse, oxygen levels, and any reactions.


After the procedure, the IV sedation should begin to wear off, but the effects may be felt for up to several hours. In most cases, the doctor advises patients to have a responsible adult take them home after their appointment and watch over them until the anesthesia has worn off. Patients should be especially careful to avoid biting the numbed area, since they will not be able to feel the pain and stop before any damage can occur. Patients should be careful with eating and drinking after IV sedation and should avoid alcohol and unapproved medications. Patients should call their doctor immediately if they have an adverse or allergic reaction.
